It is given that transition to turbulent flow corresponds to Reynolds number Re = `0.5`.

A lead sphere is steadily is steadily sinking in glycerine whose viscosity is equal to eta=13.9 P.What is the maximum diameter of the sphere at which the flow around that sphere still remains laminar? It is known that the transition to the turbulent flow correspond to reynolds number R_(e)=0.5 . (here the charactrstic length is taken to be the sphere diameter). (in mm)
